FEATURES
Space and Time Savings:
The 3340/3380 can control up to a
maximum of 8 channels in a compact 1/4 DIN package. The 1/4
DIN controller reduces panel size
and panel cutouts. By increasing
zone density, the 3340/3380 can
now make PID temperature control
for 3 to 8 zones affordable in a
multi-loop form factor, aiding
designers of control equipment to
save labor costs, installation costs,
electric panel size, and operation
cost.
• Modular Outputs,
Relay, SSR drive, Triac
or analog
• Heater Breakdown
Option with CT Inputs
• RS-232, RS-422,
RS-485 Communications Option with
MODBUS Protocol
In comparison to other multi-loop
packages, the 3340/3380 has a
straight forward user interface that
does not require a PLC programmer or other support hardware to
operate. The display, pushbuttons,
outputs and software are integrated
in this single multi-loop package.
Although all inputs are scanned at
least once per second, the display
of the 3340/3380 will display the
temperatures of each channel on
an adjustable scan rate so the
operator can view all channels
without touching any pushbuttons.
Flexible Outputs:
The control outputs are available
as Relay, Triac, SSR drive, or
Analog. The Relay and SSR drive
control outputs are plug-in modPH: 1-888-996-9258 • Fax: 615-793-3563

ules that can be exchanged individually in the field. These modules simplify application changes
and field service.
A total of 11 outputs are available:
In the 3340 four loop controller,
these can be used as:
• 8 control (4 Heat, 4 Cool) plus 3
alarms
• 4 control, with up to 7 alarm
outputs
In the 3380 eight loop unit, 8 outputs and up to 3 alarms
Alarms:
Alarm 1 is standard with all controllers. It is
mapped to all the
control loops and
can be used as
an Absolute High
and Low Process
Alarm, or as a
high, low, high
and low, or band
Deviation alarm
or as a loop
break alarm. All
Alarm set points can be individual
for each loop or can be grouped.
Two additional alarms give the
user the flexibility of having a low,
high and high-high alarm arrangement.
Heater Break Alarm:
Alarm 2 can be ordered as a
Heater Break Alarm. For loads
with multiple heaters this feature
alarms when individual heaters
fail. This provides maintenance of
a process before the problem
becomes critical.

3340/3380 Multiloop Controller
With this feature the 3340/3380 is equipped with Current
Transformer (CT) inputs. External CTs send a signal to the
3340/3380 which is converted to the load current. Two
ranges are available 0-30 Amps and 0-100 Amps. Eight
single phase loads can be monitored by the 3380 and four
single or three phase loads can be monitored by the 3340.
Digital Communications:
Multi-Memory Area:
Temperature set point, PID constants, alarm set point,
ramp to set point rate, channel used/unused for each
loop can be stored in a “memory area”. The eight memory area allows for quick changes to alternate processes
or products. The memory area can be selected via the
front faceplate or digital inputs.
With the Digital Communications option the 3340/3380
can communicate with a remote PLC or Computer via an
RS-232 interface or an RS-422/485 interface, if multiple
3340/3380s are connected. The 3340/3380s communicate using MODBUS Protocol.
Digital Inputs:
An optional ChromaSoft/SpecView software program
communicates with multiple Chromalox controllers from
a single computer. This flexible Windows based package
allows an operator
to view, change,
data log any controller parameter.

splashed liquids from rain and accidental splashing of the front overlay.
Optional digital inputs are available to select Stop and
Run or one of the eight “Memory Areas”.
